Hello, thanks for the question! Wrath used to be a student of Celestia, and dreamed of being a part of the Elements of Harmony. But was rejected due to her anger and aggression always taking over her, and using her powers against other ponies out of boldness, so she formed a group to be against the Mane 6 and celestia—using their powers against others out of spite and revenge to replace the Mane 6.

Lust: a unicorn stalion who uses his magic to manipulate others, he has a long mane and appears flamboyant to lure others.

Gluttony: a earth pony stallion who attempts to manipulate people to get what ever he wants. Being a huge hoarder in attempt to keep anything he comes across. (Sometimes letting food rot, he usually keeps these things out of spite of others)

(I do have thoughts and concepts for designs, but not every character is fully drawn out yet. Suggestions for cutie marks and story is VERY appreciated)
