Apate

I've decided that the land Asteria rules is hidden and most of my oc's live there
It is still called Athens and does have the Greeks gods and goddesses or Personified Concepts like Apate

Apate is also the keeper of one of the three main gateways to Athens.As a young filly she was quiet and very anti social more caring about beautiful things then actual pony's.She would befriend pony's but then betray them for the object that they possessed.As the years went on she discovered the cave of jewels that hides one of the entrance to Athens and became obsessed. She stared at jewels magnificent beauty and refused anyone entry to Athens or if they wanted to leave.
This became a problem as the only other ways where either in snow cave where the goddess Khoine lies who will freeze anyone who comes near or the underwater cave though many have drowned to get there
Eventually Asteria was contacted to help with the situation,even as she tried to convince the pony to leave the cave of jewels she was overcome by horror as she noticed that Apate eyes were now pink jewels.Asteria thought she managed to convince the mare round but instead Apate betrayed the Titan.Asteria shocked by the sudden deception she used her magic to bind Apate to the cave making her a gate keeper.
Her cutie mark is a poisonous gem called Cerussite I decided due to her love of gems that she should have one as a mark but I decided it should be a poisonous gem if it was possible
I adopted her from *rlynbook
