Do you see the Nightborne outside this room?
They hold us here, like mice in a cage. It is more convenient for them that we are pinned down while they search the Sanctum for my father's relics.
My companions and I can escape to higher ground with some help.
Take this crystal. While standing on a mana focusing rune, use it to overcharge a Conjurer.
Their summons will turn on them and create an opening.
Use it well, and we will meet you atop the stronghold when the way is clear.
