Is the required character by chance orange, red, or purple? Don't say Harold that's cheating

So questions for clarification on two requirements:

• 1. Character: Someone named David or Davina! They can have any design but must have that name. They must be in there, even as an NPC. Harold must also play a prominent role in your entry!

"as an NPC" is an optional suggestion for how this required character could be, right? So I could say, make the MC named it, or have a historical article about such a character or whatever right?

• 3. Location: An island. The player must go there.

How literal of an island are we talking? Can it be metaphorical or symbolically an island? :P
