A welcome to the forums from me too Mantakalar
@ML,
Another thought, though I have no idea if it could be implemented.
While mods like Green Uvirith exist, what bothers me about them is the unliklihood of having a veritable oasis in the middle of an area that looks like a blasted heath...
Yet, I do occasionally wish the tower's situation was not a bleak wasteland. Would it be possible to insert a set of conditions that enable the player to somehow "greenify" Tel Uvirith. For example, maybe the PC, an incredibly powerful mage, would be able to harness and control tremendous energies that give rise to lush growth and fine weather. But... this would not occur until the main quest had been finished (logical for obvious reasons), the PC has attained the rank of Arch Magister, and has reached Level 100 in Intelligence, Willpower, Alteration and Mysticism.
