After Cloud teleports, without issue, he sends the eyes out.
They spend the time they have surveying the area and collect the following information, which Cloud relays back to the others.
There are 32 giants in the camp, perhaps a couple more if there are some that did not come out of Bereth's tent the whole time. Bereth did come out at one point while you were watching.
Of the 32, all are male, all are frost giants. Three appear different than the others, and after some talk with Enzo, those three are non-Habololian. Bereth is also not of this world.
Bereth is overwhelming evil and he has an overwhelmingly evil staff, which he carries with him. Eleven of the giants have a strong evil presence. The rest have a moderate evil presence. After closer viewing, Cloud is sure that the eleven are some type of undead.
The giants are armed for battle, armor and weapons, boulders of ice. The undead ones have boulders on them, but no weapons.
