Danny probably replaced Amberley as my favourite character in Ice Warriors sometime during the first draft. By the time he’d become a fully formed character, I was still finding my feet with the whole mythos and the fact that each of the (now nine) Ice Warriors had a particular skill or power they’d cultivated as children.
As is probably evidenced by even the ink drawing (which is amazing work and I will try to find the artist who did these drawings for me), Danny is a policeman. And the use of the gun is accurate, because he’s actually living in the US at the start of the story, so my understanding is police officers are more likely to carry guns with them while on patrol.
Danny is actually (loosely) based on the character of the same name from CSI: New York. Obviously not the same character, but that’s where the inspiration comes from.
Danny has the ability to expand all of his senses. This can have different effects depending on where his attention’s focused, but my favourite part of this ability is what he terms his ‘binocular’ sight, which is to say he can focus on one exact point and zoom in to look at it more closely… or out, depending on what he needs to see.
