I very well may have; I do not know what a cecaelia is, but I had watched quite a few of us charge far ahead of the others before I found a crevasse to hide within.

[They have the physical strength of a wet rat at best. It's better that they don't try and fight directly, they'd just be big and in the way.]

However, if at any point you found yourself fighting alongside undead animals of the sea... that had been my doing. I was quite lucky to have found the corpse of a shark among the coral. With help from a friend as well, of course -
Even with my magic, uncovering it would have been far too difficult alone.

And I must admit, I am rather curious about that "soul energy" of yours... I have yet to meet someone else whose powers work through their soul as mine do.
