I don't know all these varbs, we can take a look and see how many we can get

varb 3909 - Knight wave training
Tutorial island
Stronghold of Security (final chest)
Natural history quiz
Kudos (talking to info clerk)
varbs (2868 - taverley, 2869 - cwars, 2870 - gnome stronghold, 2871 - crafting guild, 2872 - lumberyard) - Balloon transports
Museum camp? This ones a bit weird because the guide tells you to claim fossils by building the camp and then claim the lamp from the museum. We can probably do the camp if we want (idk if we do) but checking the lamp seems hard
