Sessions 35 & 36:

The party arrives at the peak of Irrum Vath. There they find hives with an acrid smell and what seems to be a tinkering workshop. One of the local moth-people inquired about the visitors and fluttered away once they made their request returning later offering to trade a lycanthropic kobold wereweasel for the information that they sought. Aru managed to get an alternate deal where they cleared out a ruin instead. 
The party arrived in the ruin doing battle with a group of automatons. Then entered a room with arcane ballista barring the door behind them with a large rock. A gem on the opposite door brought the ceiling down slowly when pressed and reset the ceiling's position when pressed again. The party left out the barred door and once the ceiling got halfway down the door it reset and both doors slammed open. Progressing forward the party encountered a huge automaton who told them that their existence is meaningless.
