The current in-game models, for reference

I really hope they re-use these expansion 2 models some day (I guess not the second one, as it was re-used for May). First one would be perfect for the current narrative though

Monsters which should have been Slayer tasks post-quest..

(I'll slowly add to this over time)

2017: New Ripper Demon model (alongside Menaphos)
2018: New Imp model (Howie pet)
2020: New Gargoyle model (Infernal Source Dig Site)

None of these are currently implemented, either, game-wide or at all. This includes the Gargoyle and Ripper Demon familiars.

Some more unused Mahjarrat models!

The original requirement for 'The Firemaker's Curse' (2012) was 91 Firemaking. However, as a result of player backlash, this was reduced to level 74.

This quest was developed by Ex-Mod Ana. She also developed The World Wakes & The Branches of Darkmeyer!

Fun fact:
It was stated a number of times that the Combined Catalyst Fragment (Sliske's Endgame reward) would become augmentable. It was then said by Ninja. Finally, Ex-Mod Shauny picked it up as a project in his TAPP. Unfortunately, he then left Jagex.

RuneScape: Chronicle (Chinese Version)

This was a bigger game with many more features. Fukong Interactive aimed this towards the e-sports market.
