Right, so now "acquiring more lands is unprofitable" equates to "we should totally always side with Terran because Alaster is the best guy ever"?
We could have easily joined with Phantaria and FR against Terran, without taking the lands ourselves. A much more realistic scenario than seeing anyone in D'Hara go "Oh, but we should totally save Alaster's realm, he's totally our FRIEND".
We are talking about REALMS here... You know, entities made of multiple people, with multiple and sometimes conflicting agendas? And of alliances... you know, entities made up of multiple realms, with multiple and sometimes conflicting agendas?
Phantaria acting more hostile to Terran than D'Hara was doesn't mean that D'Hara wasn't hostile to Terran. Not all hostilities are out in the open, and not all hostilities are equal. They aren't even all reciprocal.
It is very possible that many Terran nobles had nothing against D'Hara, while many D'Haran nobles had much against Terran.
If D'hara has no interest in the lands, then why is it taking them? You should also be quite aware that there is a massive gulf of political stances between Enemy and BFFs. Nobody said D'hara is siding with Terran. That doesn't make it a non-peaceful merger, because in the context of the phrase "peaceful merger" it means without an actual state of war between the two entities (not any other damn entity on the planet, or Fissoa and Aurvandil could merge because Aurvnadil feels its has no choice and is soundly beaten by Corsanctum. That is hyperbole, just to be clear.)
The simple fact is: D'hara is not currently engaged in hostile relations with Terran. D'haran has taken no hostile actions towards Terran, and has not displayed hostile behavior. You can stew and plot and scheme and plan and have goals all day long, however there are no hostilities between the nations to speak of. None. You are attempting to create a scenario which does not exist. Hostilities on a national level consist of more than just thinking bad things about each other, or hoping you get the chance one day to takeover some of their regions, or every realm in the game would be hostile with every other realm in the game.
