Oh yeah they were with the sea tentacle. Chances are, the sea goblin who would've just got back onto the ship to free the tentacle would've gotten ambushed by the elves and killed.

If Talogan did go down there, the tentacle would've tempted him into try to destroy it by mentally assaulting his mind. Ideally, he'd use a smite to do so, which would be the means in which it would influence Talogan. It would disguise itself as Talogan's god and even grant him some powers, aka make Talogan the monster's champion. And the more Talogan used it's power and became stronger, the stronger it would become and eventually would try to possess him.

But he managed to avoid that fate. So Kudos!
