Outcast's Path

I decided to play this map a couple more times (as Orcs and as Humans...). 1. In the Dungeon, everything is fine except for the last two quests - finding the remaining part of the chronicle and the dark rune. Are these quests completed in the Dungeon or on the surface? I made a backup save and went outside... 2. I probably shouldn't have included the yellow player... He's too difficult at the beginning of the game, preventing me from completing quests properly, but later he just becomes an annoying nuisance. There's nothing to gain in the early game without a Might Talent, and the book appears when the main character is already too strong. 3. I can't complete the quest - to steal the artifact from Alar. There's a centaur standing next to him, and I can't access his right pocket... 4. I feel that there's no point in continuing to play - how do I get the Ancestor Stone? It's with the High Elf, and I can't access him. The elf quests have been completed (winning on all arenas and convincing the elementals...). This was also the case in the previous playthrough, but then the stone wasn't needed. 5. Please help with a screenshot showing where to find the 4 Mayflowers for the alchemist. 6. At least approximately, tell me where the Grail is buried (I helped the Paladins, the map is open...). 7. The Dark Elf building is overpowered (I already have about 5,000 Furies). 8. Where can I find Kosko??? 9. To bring 200 Elven Arrows to Tiliir - does this mean collecting 200 Elves??? There will probably be more questions... Good luck...
