The totally serious lore of Linken

What are your theories (headcanons) on the origins and backstory of the amnesiac gnomish adventurer? What do you think his homeland is, where the Golden Flame is originally from? Are all gnomes from that place not interested in gadgets or is he the exception? Will we get answers to these questions if we ever visit Avaloren?

Quite obviously, these are silly questions about a silly reference character, but discussion is fun!
