Here's what really happened.
We had some guys out roaming in losec with some random small skirmish ships (I'm not with them). They decided to come back, and find a different gang upshipped with BCs/logi/t3ds etc etc preventing them from coming into the wh. I log on about this time, and I go scout our guys in my anathema.
This upshipped gang turns out to be odin's call, but they've already returned to their wh (we shared a mutual static). Our guys get home, and I immediately convo one of the Odin's guys, who refers me to King Creator, apparently their fc.
We lose a few guys due to it being bumfuck late, and apparently they've lost a few guys as well, due to thinking we weren't interested when we didn't take the fight in losec. I explain we were in losec skirmish ships, and would like a fair fight.
We form a tiny lotus fleet, consisting of a vulture (me) 4 gilas (1 of which is me), and 3 Basi (our basis ended up being goddamned heroes, every one). We go out our wh into our static, and warp to their wh. Turns out, they thought we were bringing more t3ds, and they had 4 svipuls and 3 scythes.
They bail into their wh, into a POS. We go through, make no attempt to catch them, and wait patiently for them to form up something else. We make friendly chat in local, and I say no worries while we wait for them to reship. We see faction BS and basi start showing up on dscan, and they eventually form 1 sabre, 3 basi, 2 machariels, a tengu and a loki. Despite us being in faction cruisers, we decide we'll stay and oblige them with an honourable fight. They warp in, and we pew back and forth for a bit. We're able to knock their stuff into low shields, but neither side is breaking the other.
We're all having a good time, when suddenly a red gila and basilisk land - promptly followed by an entire fleet comprised of 2x Rattlesnake, a Bhaalgorn, 3 gilas, and 3 basis. Since this new fleet if larger than both our fleet and the Odin's fleet, and considering up to this point Odin and us were having a casual friendly brawl, I ask the Odin guy in our chat if he wants to team up and help shoot the new arrivals (we assumed they were 3rd party). King doesn't respond, and I assume he's just busy or wants to FFA it. We jump back into the cata after we almost lose a basi, and their gang follows.
I madly ping/text, and we start to get some folks. I prep to drop my Phoenix, but forgot that I pulled painters off for hardeners, which prob hurt me quite a bit. Wiith the phoenix dps on field, I figure we can kill their bhaal and start to break what they have. We get a few more numbers as pings go out, but their neuts are hitting us hard. Shortly after my Phoenix lands, we have to break off and regroup on our hole. We get 1 more bhaal and a few more guys, and go back in. We also call a 2nd Phoenix in.
They end up primarying my Phoenix for a while, don't break it. We briefly establish control of the field until the very guy from my convo (king) comes in in a Naglfar, firmly cementing the fact that Odin is firmly on Half Mass's side. That warps in, and manages to break one of our bhaals while our 2nd Phoenix is in warp. 2nd Phoenix comes in, collapsing the hole back home. The hostile gang gets an additional 2 gilas and yet another bhaalgorn, and they're able to break out 2nd bhaal, and start winning the neut war again while our 2nd Phoenix is in warp.
We have to bail right as the 2nd Phoenix lands, and they eventually neut out/kill the Phoenixes. During the fight we were able to put a lot of their ships into armor, and even hull, but not quite able to kill them.
I'd say GF to Odin's Call, but I guess you guys don't do those apparently. Half Mass doing w/e (they don't ever fight us, the only reason they came here was because they outnumbered us >2:1 initially) is to be expected, but I always thought Odin were just another decent WH group.
Guess not, hope you enjoyed your gank.
TL;DR - Odin's Call dishonours a fair/agreed and even fight, batphones known shitlers to blob/gank us, we still fight like heroes for almost 45m despite it being ~2:1 odds against us for the entire fight (final numbers look like 23 v 16 overall, but we didn't have all our guys on field at the same time due to it being 7 vs 17 initially.
