Fair enough.

for Dex, maybe another 24 there would be just fine. And are we agreed on the lack of need for a Str score?
Wrote up the flavor text:
This appears to be a cloud of immense dimensions, so great that it spans the horizon, towering thousands of feet into the air. Along the surface of this cloud are great faces of various humanoid and other creatures; faces of wisdom and beauty. The center of the cloud pulses with a golden light, and seems to crackle with intense power.
Mortai are immensely powerful enigmatic creatures that roam the skies of the Upper Planes. Mortai are believed to be native to the Beastlands, but are sometimes found on other planes, particularly Arcadia. When seen in Arcadia, mortai are said to glow with a pulsing golden light. They are also known as the “faces in the clouds” and even the “eyes of the gods,” though they have no known connection to such higher powers. The purpose and origin of the mortai is unknown, and they are seemingly godlike in their position. Some believe them to be collections of slightly chaotic good wind spirits, or demipowers of the sky and storms. Another theory suggests that they are manifestations of the life-force of the Beastlands.
Mortai are very able creatures of the air, and are the masters of their environment. The weather around them seems to be independent of the mortai, so their role regarding the meteorologic conditions of the Beastlands is uncertain. They can, however, command the atmosphere around them with perfect control and precision when they so desire.
Mortai are usually ignored by most creatures, who either don’t realize they are there or those who know what they are and choose not to bother them. Likewise, mortai tend to ignore most activities on the ground. They are surprisingly friendly though, and do sometimes choose to interact with inquisitive creatures. They love to hold philosophical discussions and impart knowledge, often making use of their legend lore ability. Some who have spoken with a mortai have reported hearing faint voices and laughter among the clouds, as if unseen presences were listening in. Some creatures have had less friendly encounters with a mortai – they are infamous pranksters. Though the mortai mean to cause no harm, they may pester a being all day for the fun of it with wind and rain.
A mortai knows all languages, and speaks with a booming voice of wind and thunder, when it bothers to speak at all.
COMBAT
Mortai are so mighty and arrogant that they believe themselves above petty battles and common squabbles. They are pacifistic and refuse to be goaded into combat by threats, taunts, insults and the like, nor will they attack most creatures due to their actions or alignment. Because it is so high in the air, it is a serious challenge to reach a mortai to gain the position or advantage enough just to simply attack it, and then the mortai is immune to most sorts of attack. A mortai will always prefer to flee, even from obviously weaker foes, using its impressive speed.
A persistent enemy, usually an evil creature that needs to be taught a lesson, will occasionally be able to force a mortai into combat. A mortai’s main physical attack is its deadly bolt of lightning; this it may use as often as it wishes, both to attack creatures on the ground and those who fly up to meet it. If that is not enough, the mortai has an array of potent wind-related spell-like abilities at its disposal. However, a mortai has a hidden, vulnerable core of power in its center – if a creature comes looking for this it will have to face the mortai’s lethal lightning!
