About Mothership (@lore if possible )

TL;DR how much i can consider canon the mothership now.

I am about to write down the first lines of a fanfic about Veigar ( while trying to do my best with english... the challenges indeed!) and one of the biggest problems i encountred is how to deal with the mothership.

The story takes place in the past, with Veigar that grows up to be the master of evil that we know today. It does not need to be lore-bound, i am doing this more for the exploration of the character in a "how-could-be" scenario but i don' t want to part away too much from the base lore, that i know it' s in rework phase.

One of the biggest events sorrounding Veigar was the abducion of the mothership and in my fanfic Veigar actually sieges Bandle. Do you think i need to put the mothership there, to ignore his existence or just casually find a solution that does not involve it entirely and that does not exclude or not its existance?

I will tell you this: to me, the mothership was garbage; not as the mothership per se, but because for me it was a lazy solution for a wtf thing and shallow weirdness. But a lol fanfic is a lol fanfic, and i want to keep at least a bit of canonicity on if it reveals to be a good cause. Toughts? ( sorry if moso lovers gets offended, i will repay with veigar bashing Rumble suit with a meteor if it ends well )
