An Elf

In the elven underground, at least a good half hour of searching had passed. The undead proved to be better hiders than the elves initially expected. But that didn't mean they would never be found.

"Over here!" An elven warrior shouted noticing an oddity behind one of their stone crates.

"Did you find-!?" Another nearby elven warrior was about to ask loudly before noticing the nature of their operation. They had to be stealthy about this! The undead creatures shouldn't figure out they had been found.

Otherwise, the winged one just might fly out of the hole it dug itself into with the other in tow. The current number of elves in the surroundings meant that that winged undead could injure or kill some of them and make off with ease.

Actually, even without attacking escaping wouldn't be too large a problem in the case they were overestimating the undead's skills.
