This is related to a picture Talcom did a while back. (This picture is also an old one)
Forground is Black Fire - my first MLP OC - there will be more of her around.
Bottom left is Trail Blazer (nephew-in-law) trying to blend in because he didn't want to be left out.
Background right is Talcom after being temporarily turned into an Alicorn.
Background left is LegendPony - part of the original picture of Tal's.
