Golem Room

This room has a magnificent runic engraved door at the end of it. Above it, it reads in dwarven runes “ Earth and Stone”, which is a religious hymn to honor the dead.
Last time, the party attempted to sing the hymn and the door opened, releasing a Golem, Stone Guardian that cried out “death to those who defile the tomb of Ragnar Stormhaven”. Which was defeated.
The entrance from which it came had a lever in the rock formation, pulling it revealed a staircase that leads down. When Graardor reached the halfway point, the stairs smooth down. The slide seemingly leads to a sort of refuse pile.
Lyraëlle Aervàndys did notice a strange wall and stalagmite.
