Ignis Savlinn is a bright young lad who wants the best for everyone and  wants to help others as much as he can. He's an empath at heart and  cares deeply for the feelings of others and would go out of his way to  make them laugh even if that means making a fool of himself.

Despite being held from two stallion fathers who are very well known in  equine modern society, Ignis is often embarrassed when others bring out  his parentage. He's just your good old friendly neighborhood delivery  guy, he's not some sort of all powerful pony. 

Ignis has arachnophobia, its not one he often tells others about but he does flee at the mere sight of one

All unicorns have the ability to use their magic for their every day to  day lives but Ignis is different. Despite himself being a unicorn he  doesn't have any magical connections at all, he can't use a simple spell  to levitate a book or open a door. He might as well be considered an  earth pony with how much his magic isn't intact. 

With his father's connection to Princess Twilight, Ignis was able to  meet the other kids who lived in her castle including Ares and his  brother. Ares and Ignis were quick to make friends and both bonded on  their love for mischief and scaring their parents by playing hide and  seek in the large library.

Despite his lack of magical abilities, Ignis is rather content in living  his life as a normal pony. Though he wouldn't lie and say that being  the only pony, to his knowledge, being unable to channel magic as he  should but that doesn't stop him from trying to be his best.
