Work, marriage, baby....that's about the quick gist of it. lol Life's real good. And yes, it's been years for sure. 

I'd definitely be interested in sharing ideas and building new characters to fit into this setting for sure. However, since I'm a guy with a full life, it may be slow going for me. Being married with a little babe takes up my time and my ideas in many ways. I have several ideas of course that I'd like to share with you guys. I see that Nightmare is kind of a legend/myth in this setting, which is an interesting idea. If you read about the Triad of powers of the Multiverse that I posted a few days ago, you will see Nightmare consumed OMEGAN and became one entity, thereby (in a way) resetting the Multiverse. This could of caused a multitude of events to ripple in the Multiverse. Anyways, it's good to be back on the old drawing board sort to speak, to get the ideas churning. It helps to get those ideas realized when you have other like-minded individuals to share with. 

I do recall the Saurians as being civilized and orderly so we can potentially fit them into the Ordo Imperium as a race. Feel free to discuss this in the plotting thread I just started.

And no worries about time constraints. We all lead busy lives, that definitely comes first.

Let's see if I can organize my thoughts and address everything.

Okay so how this relates to Multiverse, we wanted everything we had to matter and build on it without it just being Multiverse again or Multiverse 2.0 or what have you, at first we had no real connection to Multiverse but overtime that laxed and we started going with Multiverse characters reborn here in this new setting, so the Multiverse became and legends before time, another existence, tales that never were and yet some how were.

So we moved a lot of the old Multiverse characters and things into fables and myth, some are here, who they were but some how disconnected from that, like the Multiverse was just a dream of another incarnation, and a little of that nostalgic crossover ambience is used for certain characters and moments to make them feel extra special, like reveries, the hidden layers.

But anyway it gets a little more sorted when it comes to Omgean because I actually have a fairly complex story in this setting that involves him and I'm pretty sure it could be adapted easily to fit with your idea. Obviously in the end of the old Multiverse Omegan was defeated but we never really talked details about what really happened to him, so I improvised with the story that he was utterly destroyed by the Ex-Box (referred to in this setting as Es'Kailieon's Cube), however that's the outside perspective, inside he was utterly banished from the Multiverse, which could explain easily how Nightmare was able to absorb his essence in that reality.

However inside Es'Kailieon's Cube he remained trapped, until much later that this new reality came into contact with his essence inside the Cube, he probed for ways to enter this reality but couldn't find such a way, it was a reality without a connection to him, he couldn't exist in it.. at least.. not as himself. Through use of the one of the Lost Children a door was opened, a vessel was made, something capable of communing with him and giving him agency in a new destiny, he was incarnated into the second half of the Heart of Dark Legacy, a virtually perfect name for his future, and although he did escape the Cube, he is not altogether exactly what he was, part of that could be due to his disconnection from the Multiverse, his last exchange with Nightmare, existence in this new reality, possibly all of the above, etc.

As for a Saurian type character I'm sure we could accommodate whatever needs you have for it, in this setting all dragons originally came from the world of Aval, it's their homeworld, however their first crossing over into Aaru was in the primordial times, as such they've integrated quite thoroughly into the native culture and developed new cultures entirely independent of their homelands, if your idea finds a common ground with D4's Imperium culture I'm sure something can be arranged. Most saurians on Aaru fall under the Beastmen Empire where their long time leader established his rule around 7,000 years ago when the mega Empire of Bolas broke up that use to encompass the Ordo Imperium and the Beastmen Empire. However, there are a fair number of more direct saurian kind that don't fall under that rule, lots of free agents and several groups of dragons and dragonkin that subscribe to either personal ideals or fall in with other factions like the Eastern Kingdoms, Tel'Chak The God of Monsters, The Nightmare Dragons, etc.

Also no worries on time, honestly that's the way we prefer it, good stories are better given time and development. I don't like the feeling of things being rushed, I know if I don't get around to anything here for a week it's not gonna fall apart.
