Guest System for Trusts

I know the Trust system isn't for everybody, but I personally loved seeing the NPCs talk to each other and interact with the environment during my run-throughs of the MSQ dungeons! :D Then after completing the main scenario quests I was sad to see Lyna and the Crystal Exarch disappear as options for the first dungeon!

If you don't want to break immersion by just having every fan favorite NPC as a trust, could we do a guests system where a relevant NPC in certain dungeons could be used as an option? Lyna and the CE are already fully capable in Holminster Switch. If we were to use older dungeons as an example: maybe something like a Haurchefant in the Vault or a Hien in Bardam's Mettle. Going forward I feel like there could be several interesting opportunities!

Side note: I think it's great that the NPCs look like they're taking a much more active role in our adventures and the Trust system is a great alternative that fleshes them out a bit more as characters (imo). Cheers!

I miss Lyna!
