Starswirl and the Sirens

After the fall of Tambelon and Grogars banishment into the void, through the eclipse, beyond the gate of stars, and his ascension beyond the realm of common unicorn-ponies, Starswirl made his way to the remains of the fortress of Tambelon. Not much was left. The greater part of the dark structure was banished to the void along site Grogar and what was left of his Army.
The entrance to the dungeons were still intact, and so were most of the hidden hallways deep under the ground of the Bad Lands. Behind on heavy dark oak-wood door he  found them. They were the size of foals but the lower body was like that of a fish At first he thought they were Shoobadoo, or commonly known as Seaponies, but Starswirl soon came to realize they were not. they were something new, another one of Grogars foul creations. He should have got rid of them right there, but as he saw them there alone and with nothing to live or hope for he could not do it. He lead them out of the dungeons and to them under his care.
If he only had know what his pity would lead to in later years.
