Contacts
Underdark Explorer Contacts
As an Underdark Explorer, your journeys into the lightless depths have forged a bond with someone who shares your understanding of its dangers and mysteries. This contact could be an ally you encountered in the shadowed tunnels—a fellow explorer, a merchant trading rare resources, or even an Underdark inhabitant with a begrudging respect for your tenacity.
Your contact might be a deep gnome cartographer who relies on your reports to update maps of the ever-shifting tunnels, offering you information about hidden paths and potential threats. Alternatively, it could be a myconid sovereign who regards you as a trusted outsider, sharing spores of communication and glimpses into the vast fungal networks. Perhaps it’s a drow outcast who once guided you through perilous caverns, their knowledge of the Underdark’s societies invaluable but fraught with danger.
This relationship is rooted in mutual survival and respect. Your contact may provide warnings of territorial predators, access to hidden resources, or guidance through treacherous regions. In return, they may call upon you to retrieve a lost artifact, negotiate with rival factions, or lead them to safety when the Underdark's peril becomes too great. Trust is rare in the depths, but with this contact, it has become an unspoken lifeline.
"The city's forgotten corners whisper secrets to those who listen—every shadow, every creak, a clue waiting to be uncovered."
