Xanrym sees that the insignia is very old, probably from a time when this city was ruled by the drow. Apart from that, the operation of the door is a mystery.
Khessa sighs; she was hoping the way to open the passage was more obvious... but she quickly turns her blue eyes to the wizard of the party and suggests: "Theldrin, if I remember correctly, we already established that the glowing gold stain is magical... You know a ritual to learn the details of a spell in progress or how to use a magical item, right? You could try casting that ritual on the gold stain... Maybe you'd discover how to use it."
I think that Xanrym could re-roll if he wants to. Technically you've just given Theldrin advantage, not added your own modifier to the roll.
Xanrym - Investigation: 14
Trying to figure out the operation of the secret door in the tannery.
(OOC: Hm...decent but not great. Since our whole plan depends on getting through this door, I'll use Xanrym's Heroic Inspiration to re-roll that.)
Investigation: 11

Hearing Khessa’s question, Syllen speaks.
“I can quickly check if there is anything magical in the area.”
With that Syllen casts Detect Magic and will look to see if anything about the wall or in the room is magical.
