Mods should agreed on a certain day to do a drop party event in the Camelot party room dropping Christmas crackers / party hats to introduce Rares into the game.
Interesting idea, but unfair to people who can’t plan to be online when it happens. Anything like this should be done over multiple days to give people an opportunity to participate.
Another idea: Put special days through RNG to spawn a rare on a tile:
Pi day (3/14):
- The number “3.14”
- Some range of numbers to reference every in-game walkable tile
- Pass both into an authentic RS RNG machine
- The result references a tile
- Website would report a vague area as to where the tile is
- Everyone wanting it would search the area until someone finds it
Tile could be something behind Brimaven pirate’s bar and the reference being “where mateys go near luverly liqueur” (hinting Karamja with the Ape Bite barcrawl reference, alcohol, and pirates; what other area could that be 
)
The rare has to be placed by the game itself (not spawned to a tile by a logged-in player or inventory-dropped by a player/mod/admin walking to the tile; server has to do it). Whatever tile is referenced by the machine is where the server will spawn it. And open-source code to prove all that (I think it’d be more authentic feeling though and think it’d be cool to have a rare that was spawned in the world like that!)
I don’t like the idea of party room for rares (the party room itself is more for players and good-will vs introducing stuff people mainly want for notoriety) and don’t like rares being distributed equally (anyone showing up gets it like a participation trophy).
