Going underground is the only option for reaching this location, as it is inaccessible from the surface. In this area, there is a puzzle that is comprised of stele flames, and in order to take on an optional boss, it is necessary to figure out how to solve the puzzle by making use of the stele flames. This area is infested with a disease known as the Scarlet Rot, which, if your character contracts it, will have the same repercussions as being poisoned with a more severe kind of toxin. The Scarlet Rot can be found throughout this region. The objective of this quest is to vanquish Starscourge Radahn and demonstrate how the power of his Great Rune can be utilized to one's advantage within the confines of the Divine Tower of Caelid.

By going to Fort Haight, you will be able to get to the crater that was produced as a result of the crash. 

This location can be found in the part of Limgrave – Mistwood that is the most southeasterly (and is therefore relatively close to the entrances to Minor Erdtree and Siofra River Well). You will be able to pinpoint the location of the crater if you go to Fort Haight. In point of fact, this is also the location from which one is able to obtain the Mimic Tear Ashes, which are generally regarded as being among the most powerful Spirit Ash summons that can be called upon at any given time within the context of the game. In addition, this is the location from which one can obtain the Mimic Tear Ashes. Because this summon creates a clone of your character, it will make your life a lot easier because it scales its damage based on your stats and the weapons you are equipped with at the time that you cast the summon. Additionally, because this summon creates a clone of your character, it will make it easier for you to deal damage to enemies. Dealing with foes will become a lot less difficult for you as a result of this.

As a direct consequence of this development, your capacity to vanquish adversaries and achieve other objectives will be significantly boosted. Your capacity to overcome challenges and accomplish other goals will be significantly improved as a direct result of this progression in the game. You must first demonstrate to Royal Knight Loretta that you are in a position of superiority to her before you will be granted access to Caria Manor. Only then will you be granted permission to enter the manor. After that, the gatekeeper will let you into the manor if you've earned his trust. The inverted Carian Study Hall, the Nokstella Eternal City, and the Lake of Rot are some of the locations that fall into this category; however, this list is not exhaustive.

Within this expansive view of the surrounding area, the viewer is able to make out Mount Gelmir as well as the Volcano estate. You can reach this location by taking the road that winds to the west and eventually reaches the edge of the Altus Plateau from the northern part of the plateau. If you continue down this path, you will eventually arrive at the location you are looking for. The next part of the process that is going to be under your control is going to be climbing the path that is going to lead you all the way to the summit of Mount Gelmir. If you keep walking along this trail, you will get to a lookout point that gives you a view of Volcano Manor at some point in the future.

The residence of the Royal Family as well as the political and administrative center of the Principality of Leyndell
If you leave in an easterly direction on the main highways that cross Altus Plateau, you will be able to get to the Leyndell Royal Capital whenever you are ready to (or whenever you decide not to), no matter where in the world you are. During the upcoming conflict, you will face formidable adversaries who have built formidable fortifications. This will make your job extremely difficult. You have the option to go to Roundtable Hold and talk to the Dung Eater, who is a red non-playable character that can be found in one of the rooms there. If you choose to do so, Roundtable Hold will be opened up to you. If you make that decision, the Roundtable Hold option will become available to you. Before you take part in any of these activities, it is imperative that you finish this step first. Not only is it strongly recommended that you do so, but it is also required. In spite of this, if we want to be successful in accomplishing our goal, we need to make it our top priority to storm the castle and kill Morgott, the Omen King. Only then will we be able to move on to the next step.

In relation to one another, the Mountaintops of the Giants and Miquella's Haligtree are the two locations that are being discussed at this time.
After that, Melina will give you instructions that will direct you to leave the capital city through the eastern exit of the capital city. This will come after the previous step. You will need to first obtain both halves of the Haligtree Secret Medallion in order to be able to use this important item, which will permit you to enter the Consecrated Snowfield. Once you have done so, you will be able to enter the Consecrated Snowfield. The Haligtree Secret Medallion Challenge needs to be finished in order to accomplish this goal. You will be able to carry out this action once you have completed the task of solving the puzzle. You will, from this point forward, be in a position to continue your exploration deeper into the Haligtree as a direct result of this, which will allow you to do so. As soon as you get past this point, you should be able to make out a large cauldron that serves as the location of an important decision that needs to be made regarding the future of Melina. This choice needs to be made before you can proceed. You will not only have the opportunity to defeat the Godskin Duo in this region, but there is also a hidden boss here known as Dragonlord Placidusax, who you will need to defeat in order to proceed.

You will need to carry out both of these tasks in order to finish exploring this region completely. In a short time, Godfrey, the First Lord of Elden, will assume the role of your foe and do everything in his power to prevent you from achieving the objectives that you have established for yourself.

One more thing: once you have vanquished the very last boss, you will find that you have been transported to a stone platform that is home to a Site of Grace as well as a statue of the Fractured Marika. This will be the last thing that you will need to be aware of. You won't be able to move on to the next level of the game until you have completed the very last obstacle that it presents. You have reached a point in the game where you are given the option to choose an ending from among a number of different ones that have been unlocked and are now at your disposal.
