Uh hmmm. Gil can record what he finds and they can they discuss it. If further needed, I guess they could even have Jian Cheng swim to the bottom of the lake and then have Vanya move the water for him to get a longer look (assuming Vanya is abvailable to assist)?

I mean, Raven could theoretically evaporate the lake, but they need that lake for water, right? And Gil isn't into doing mundane things with Raven unless it seems like that's a last resort.

Would Raven be able to find anything concerning the corpse in terms of supernatural type stuff? I'm super cool with waiting until threading is done for details, but it would be good to know if Raven could potentially contribute anything.

Either way, I think Gil would want to take the info they both get and go search for any missing persons that may known about if it seems promising that he could be identified that way.

Jiang Cheng would have to fill Gil in a bit on things, such as who Annur is and why he matters, because Gil hasn't yet truly realized the necessity to understand all the variables in their situation as of yet.

In fact, he would probably want to have the ones planning to go visit Annur's troops and question them about if they are missing someone? If that's like a possible thing to work timing wise?
