Torchflower for Deep Dark Portal

I think it would be cool, since the sniffer and the warden both seem to belong to the same ancient age where smelling was used more than seeing, if the sniffer was the key to lighting the portal found in ancient cities if such a portal is ever added. Due to the torchflower's name, you could light it with a flint and steel or fire charge and a special animation would play out where it burns up and drops some sort of unique item (torchflower ash?). This could be crafted into a special type of fire charge by replacing the coal in the usual recipe, and when used on the portal could light it. Or any other method inolving the sniffer or torchflower (e.g. sniffer digs up something other than a seed for lighting it, another ancient sniffing mob involved with it somehow, etc.).
