I had a hexagonal end table in my room, and when my 2015 sets were still together, I had each toa and protector pair facing outward on each side with their corresponding skull spider behind them, and LoSS in the middle.
I myself don’t have a shrine for my BIONICLE sets, but in my cousins new house he has a ledge in one room that he put all his BIONICLE sets on. And he also refers to that room as “The BONKLE Shrine”
I guess you could say I have a few shrines, in a very loose sense. I have a few posters hanging over my bed, the bookshelves where I keep my collection, and there are always a few on my desk that I cycle in and out.
