This walkthrough provides a complete solution to Rhiannon, Curse of the Four Branches. As with all my walkthroughs, I have concentrated on the clues to the various puzzles and the logic used to solve them.
Spend time in each new location and take note of all the items you can interact with. In many cases nothing can be done with a particular item until you have found something else, been to another location or need it to solve a puzzle. To avoid 'spoilers' these items are only dealt with in the walkthrough as and when they are needed.
In addition to the map found in the game, I have included a few of my own as well as detailed directions to finding certain objects or locations where these may be difficult to find.
