Kiaermaer

''In times of old, the waters that separated lands were uncharted, vast and perilous. Crews would venture out, cargo on board and high hopes for riches and glory ahead, and would not see the rocky horizon ever again, lost in the deep for all eternity. Others will draw into port, with the sails in tatters and with tales of creatures that, in the middle of the seas with naught by water from horizon to horizon around them, led them back home. They told stories of fish that leaped above the water and would hover, beating two pairs of wings just behind a great hammer of a head, shoals of which would surface and guide the ship to land, some even pushing their vessels along. They haven’t been seen for years, ever since the maps were charted and ships didn’t get lost any more.''

The Kiaermaer (Guides of the Sea, Baykonian) is a peaceful mob of the seas of Rathnir and Eldham. They have played at the bottoms of our oceans joyfully while ships knew their way. They play along the surface occasionally, and those who declare they have seen the antics of the old mythological creatures are called mad. They hunt squids of all sizes within the depths with what is said to be some of the greatest accuracy of swimming and flying in the mob kingdom using its four rapidly beating wings for full 3-axis motion at the fraction of movement.

They lie at 2.5m (blocks) long, with a wingspan of similar magnitude, though the wings can be folded back in to squeeze through a gap. Their head is a block tall (actually 0.95 of a block) and is fronted with a ridge of bone used to ram their prey and their threats.

Be warned, if you anger the shoal, you will suffer a swarm.

Mechanics
They spawn in shoals around stationary boats with a player nearby, granting night vision. They can fly, hover and swim. They do not stray far from the water's edge.

When fed the "correct fish" (yes im keeping this a secret, the admins who add this can choose whichever fish item they like), they will breed and be considered friendly and will grant temporary conduit power.

If you feed it the wrong food (any other food item apart from the "correct fish"), they will apply the blindness effect (or darkness for 1.19) and swarm around the player, swooping and dealing small amounts of damage each.

When bred, they will lay eggs on the sea floor, which can be picked up and placed in water. When the child grows up it sheds its plates and its baby crest which both can be used to craft tools, weapons, armour and (hopefully) more.
