Thank you! Those are brilliant prompts and I've added them to the list. (And you're right, the EotW has some fantastic guest characters - David Whitaker is always so good at that sort of thing).

I'm hesitating, however, over the War Chief is the Master prompt because while the War Chief is eligible, the Master is not and if the War Chief actually IS the Master, I'm leaning towards ineligible here. But I'll think about it, especially as someone would like to claim it. (I think robot!Lucie, being presumably a completely separate being would scrape through.)
