Weird idea, but maybe using the vision trick Vince described in combination with The Aaron's Token Condition Script could possibly work. If you assigned the decoration tokens to the mage's player and gave them vision, you could have this aura of player tokens following the mage token that all give the mage vision. Since the tokens will automatically move past dynamic lighting barriers, they should grant sight that way. EDIT: Just tested it out, and it seems like what I suggested does work, but actual practicality could be up for debate. You'd have to make one token for each direction, and also have to make a token for each range within that direction. You may be better off just using a vision token like Vince suggested and just be mindful to drop it onto the tabletop whenever their tremorsense would find something of interest.
