Hello, I reached point where I don't know where to go. I'm currently near far tower area, where's place to sleep and near war room and patroling guard with cypher message. I need to collect guard greaves in order to have full set, and then I plan to go to prison, I talked to Silas, talked to Gusto and Fatale, I collected 9 roses and found 5 beetles. What to do, where to go?

Ok but what are the differents quests available apart the guard's armor? How many parts of tha armor do you already have?

If the guard greaves are your last missing piece, you have to go into the woods and left. There will be another bridge with a door at the end. Behind that door a guard patrols the looooong spiral stairs. He has the armoury key, which you need to get the greaves. The armoury is at the bottom of those stairs and the chest with the guard greaves is in it.

If you need a tipp how to best get them undetected and get to the armoury at the bottom of the stairs undetected:
When he stands near you at the top, sneak up to him and steal them. (It took me 2 tries to do, because I was too slow on the first try.) Once you have them, sneak after him, when he goes down, but wait on the stairs, opposite to the wall with the armoury door (he stands in next to it). When he walks up again, wait until he starts noticing you, then jump down the stairs and hide underneath them. (If he gets alarted, you can hide in the cupboard in the armoury, if you manage to stay out of his sight long enough.) You should be out of his sight. Shortly after you can calmly walk up to the armoury door and open it.
