Once entered, the player will meet three Ancient Spirits. The right one, named Ancient Spirit of Strength, grants an offensive buff whereas the left one, named Ancient Spirit of Life, grants a defensive buff. Only one of the buffs can be received.
The middle one, named Ancient Spirit, is where the player can talk to it about the place, leave the instance and most importantly, choose the portal of the instance. Once chosen, the player can not undo their choice.
