Druidun rumours

What characters may know, or think they know, about Druidun Castle/Tower and the surrounding region of Pelshire:

1. The Mad King was driven insane by demonic possession, and opened up a gate to hell itself under Druidun; if you can recover the Shard of Acheron, you can command the demons. 
2. There is a powerful Ley point, a convergence of the rivers of magic energy that undergird reality, beneath Druidun, which is why the castle was built there. 
3. Bandits are kidnapping people for a necromancer to turn into undead minions, and send them back to devour their families. 
4. Processions of the dead pass through the villages at night, and any they encounter are doomed to join them. 
5. The castle of Druidun is cursed and any who go there return… changed.
6. The wizards claim to have purged evil from the castle, but they lied. Something is festering there in the dark…
7. The Eldritch Veil was overwhelmed by the infernal magics they unleashed beneath Druidun. 
8. The Eldritch Veil leader was the reckless Archwizard Pimrith, who had been expelled from the Order of Magi for crimes committed beneath Druidun Castle.
9. The Eldritch Veil conducted forbidden experiments in the magic infused tunnels of Druidun.
10. The magical energies beneath Druidun drove the wizards insane, including Pimrith. It also fuelled unlife, bringing many dead things, that should have remained that way… back. 
11. The nature of reality deep beneath the castle is changing. Restless spirits have used the astral nexus to return to Arthea. OR Eons ago, the Druids of the Arth built a temple on the site of Druidun Castle. In catacombs far beneath, they constructed sacred chambers, imbued with powerful magics, havens where healing waters and wisdom flow, and one can commune with the petrified roots of wise ents. 
12. The energies beneath Druidun are drawing the attention of powerful entities from other dimensions. Ghosts, demons and mad visions now haunt the land.
13. A mysterious priest and his followers from Setesh have been seen in Forksbury, and they arrived with a large box, which was carried by wagon from the city docks. The priest is known only as The Seteshan. People say he is part reptile, that he can turn into a serpent.
14. Magical devices that have not worked in ages will work in the dungeons beneath Druidun now, feeding off the astral nexus energy.
15. The wizards caused a cave in to seal off the nexus and hoped for the best. The whole thing has been covered up. 
16. They say that the spirit of the Mad King has returned from beyond and now rules the catacombs of Druidun. 
17. The energy beneath Druidun is rumoured to be chaos incarnate, incredibly powerful… and even more difficult to control. 
18. Plants in the area have been withering and contorting into dark parodies, crops have failed and a thick, curling black weed is now common. The corruption is centred around Druidun Castle. 
19. Winged malevolent beasts prowl the skies at night over the villages, including a dragon, and no one dares go outside in the dark. Even patrols by the constabulary have ceased.
20. Many famous people were buried beneath Druidun in the extensive crypts, including the famed world explorer, Aldric Haven. He is said to have been buried with his beloved maps, which detail kingdoms far and wide.
