I wanted to follow-up on this in case folks wanted to make this a community project with our assistance. The starting file is located in your installation folder at: resources\interface\themes\default\defs

Most of this is beyond the scope of this thread to discuss, but you may notice links (ltut) that reference several files:
  • Encyclopedia (IstarianEncyclopedia.def)
  • Multischooling (Multischooling.def)
  • DragonInformation (Dragon_Tutorial_Info.def)
  • Communication
  • Death
  • LevelGain
  • WideWorld


These are all tutorial files that you can browse and edit and which can link to other tutorial files. The last four on the list contain simple information about each of those topics, but the first three contain more links to break the topics down further. All tutorial files are located in your installation folder at: resources\interface\tutorials

The encyclopedia was meant as a repository of information about topics such as geography, lore, monsters, and schools. It breaks down each further into types of monsters, types of schools, etc. It even contains a "General Topics" section to discuss things such as Abilities, the Camera, Cargo Disks, Chat, Spells, Techniques, Shrines, etc. The Lore section was meant to contain descriptions of things such as the races, the timeline, the pantheon, events that have occurred in the timeline (both pre- and post-launch), etc. Those files are located in the tutorials folder and are named Encyclopedia_<name>.def.

To add more files that are referenced, you'd need to edit the UI_Tutorials.def file. There's a section near the end of the file named "Encyclopedia Triggers" where you can add more. Remember, you have to place new files in resources_override or the client won't pick them up.

Common tutorial things such as the arrows, window highlighting, etc will work in this. However, there are limitations and you should be careful when using them (bad things can happen if you target a window that closes or is closed, for example). Finally, there are also character limitations in the blue boxes and you can't do things like bold, underline, font changes, or colors.
