#so solar's the oldest model but technically he's the second youngest because he was only online for a few weeks

[itsahotminuteinbetween]

alrighty then, written explanation it is because I've been trying to draw it out for the past couple of days but designs are not fun to hash out while working on other things but anyhow!

some quick notes on the celestial symphony au prior to events that take place:

So, in canon, the Daycare Division started with attendants Sun and Moon-however, in this au, the theatre and daycare attendant line started with Eclipse models-the body was made by the creator, but the software was left up to FazCo. While functional, there were some slight errors with the first prototype during testing prior to its release into the public, such as confusion over orders and unwritten personality guidelines, to name a few. As a result, the first Eclipse prototype was scrapped within the first five minutes of its activation. Unfortunately, it wasn't properly shut down when trashed in Parts and Service, and finally turned off after running out of battery within a span of a few weeks without motor control activation to reach a charging outlet.

The second model (aka the og eclipse from the sun and moon show) built did not have these errors and was green lit to be released into the daycare, with smooth sailing for about 8 months before an incident occurred. There appeared to have been an overlooked software issue that messed with the personality of the attendant, causing it to become more irritable and quick-tempered, with certain parameters stressed too much and overruling others. A guest was gravely injured (to say the least), and the Eclipse model was scrapped in Parts and Service like the first.

With the evident failure of the Eclipse models, FazCo decided to split the code into two separate AIs-Daycare Attendants Sun and Moon, who were much more successful than their predecessors. Two years after their creation, Lunar was added to help with the younger children. At this point in time, the Daycare is doing alright, but the profit isn't enough to justify the investment placed in corporates' eyes. To cut back on cost, human staff manning the theatre and assisting in the daycare were replaced with the previously scrapped Eclipse models, which was...a bit jarring for everyone involved.

The first prototype, aka Solar, is tasked with manning the theatre, while Eclipse is sent off to be of more assistance in the Daycare, which results in some rising tension as both models realize how quickly they'd been replaced and how little they're actually needed. Sun, Moon and Lunar are hesitant to allow Eclipse to handle the children due to his less-than-stellar history with them, and Eclipse himself struggles between anger and betrayal over his replacement and the fear of a repetition of his lash-outs that resulted in his decommission. To avoid the other models, Eclipse typically stays away from that part of the plex and hangs around the theatre to bother Solar and help out with some menial tasks.

(Solar and Eclipse are on okay terms here for the most part-though Solar is a bit bitter about the fact that he was replaced so quickly without being given the chance Eclipse had, he recognizes the similarity in their situations, and they're a little closer than they are with the other attendant models. Sun, Moon, and Lunar don't mind Solar much since they couldn't really find anything about his past that was as bad as Eclipse's, and he stays out of their way for the most part. They're on good terms, with Solar helping Moon with any technical issues that should arise and entertaining Lunar after closing.)

This arrangement continues for several months before Earth's arrival to restore the theatre under the threat of the entire Daycare department being shut down and all the attendants scrapped.
