Long ago, i saw a suggestion that there should be a banner available, for guilds to sell to their members, that displayed the guild heraldry (matching the tabard). Perhaps this could be implemented with the additional function of acting as a portal. I.e. the one placed by the guildmaster in the guildhall would define the entrance location, and other members could place copies in their homes to reach it. Walk up to the banner, “use” it, and you’re at the guildhall. It would not need to send you back. Returning home is already easy enough.
Placement would need some restrictions (no arrivals 50 meters above the voriplasm pit) but that already happens when placing crafting stations, to ensure they are usable.
Let’s discuss, including how to feed the voriplasm if this won’t work.
