There was a reason why Yve was the one assigned to protect Hal and Liora while Lucien and the others hunted Arran down.
She was a master of the earth element, and there was a corpse they needed to tend to.
Monk had been nothing short of a great comrade.
The least they could do for him was bring him back to the capital and give him the proper burial he deserved.
And so, Yve made a temporary earthen coffin for her fallen comrade, retrieving a spray solution in her item box spell and using it on Monk to preserve his corpse.
She then closed the casket with another layer of hardened soil.
As much as Yve wanted to bring Monk along with them while they searched for a decent resting spot, she could only leave him here.
Thanks to the special spray solution, he wouldn't be noticed or bothered by the beasts and monsters in the area, anyway.
They would return for him once Lucien and the others came back.
