"Came to die, brat?" Asked a rather gigantic looking lion with a human head, a cheap imitation of the sphinx, all the look but none of the nobility. To his words, Yunan just shaved off his mane with his soul bound divine sword. He waved his hand the sword returned to his side, he smiled properly and used his most diplomatic voice: " I came here to declare war, anyone; who is not the head of the council or the person who can speak for the entire council, will be killed, I have no time to talk to inferiors".
The sphinx imitation roared and launched a fury of attacks at Yunan who stood there and took them, sneakily consuming some of the energy in them to better understand it, the barrage of attacks died out a minute later with Yunan now looking like a metallic dragonborn, although his armour was no longer sufficient for defending, Yunan needed to hide his defences with something like an armour, he needed the council to underestimate him and think he was relying on tools.
In reality, Yunan had adapted to the attack moments after it started, the energy he digested guided his own mana on how to defend and avoid damage, he changed his form and used his armour to make it seem as if he had to put some effort into defending.
Once the sphinx imitation was spent, the attacks stopped, revealing the uninjured Yunan, there was a gasp and then a sword flashed. The human head separated from the lion body, and before it could exclaim it was consumed by Yunan, not a trace left of it. Yunan made a burping sound, before taking his armour off.
"So, who here can speak for the council and who among you has a death wish?". This was Yunan telling them that annihilating the whole council may be out of reach, but he can certainly kill a few and escape with his life and that his war declaration had some unknown purpose behind it, he was merely enacting his plan out, it was strategic for him to make them overthink all of his actions, he was going to do the same to the avatars, he just chose the council because of their tendency to underestimate others.
"The head of the council is in secluded meditation, I can speak for him and the council, please relay your message or get to fighting, we don't have the patience to do both" the calm voice indicated the position and strength of the speaker, he too liked to speak in a way to make the listener believe he was stating facts, except that he always put others underneath him in terms of power or nobility, making his words sound only arrogant and filled with envy.
"Just wanted to let you know, I am going for the avatars before coming for you, I plan to subdue them and bring them here as part of my force, therefore, please wash your necks, my blade is coming for each and every one of you, just to be fair, if you wish to hinder me a bit, feel free to kill the avatars for me, or maybe ally with them. That would help me a lot, that is all."
After saying his piece, Yunan pushed his way through the gods surrounding him, not forgetting to consume some of the ambient energy surrounding those who he touched and pushed away. He had learned early on to not show off his power, intimidating others with your leaking energy was only valid on weaker opponents, the ones who are equally strong or even stronger can use that bit of leaking energy to utterly decimate you.
Leaving the divine realm of the council, Yunan went to the avatars and did the same, making sure to emphasize that he was going to use the subdued power of one side on the other, both sides knew that a scheme was already in motion, but they did not know what Yunan would do, he was crazy enough to make all the gods prisoners, what else won't he dare to do?.
To their dismay, Yunan usually did not lie, or exaggerate, if he said he would subdue one side to deal with the other, he was going to do it, and the only way to stop him was to due the same thing, subdue or enslaved each other, they could have united, but neither the over-gods nor the avatars were prepared to risk betrayal from within their own ranks.
Since Yunan was planning to use something on them, then they can destroy it, as it stood now, neither Yunan, nor the other two factions could kill each other outright, they had to weaken one side or absorbed a faction, Yunan was out of the question because Dreamscape was literally a land where nightmares dwell, thus he could just turtle inside and let them dry out as he shipped at them slowly but surely.
Since that only left one other faction to be absorbed, both the over-gods and the avatars turned to each other and started a full-scale war, meanwhile, Yunan was slowly converting their divine realms, making them empower his forces instead of their owners.
The entire reason for this declaration of war was to sneakily plant a seed inside each realm and hide that with his wanton destruction and killing, the seed contained some of the essence of Dreamscape, these seeds would grow in power by absorbing the dream energy of the gods occupying the realm, and as they grew, they would infect the realm with dream energy, merging the realm with Dreamscape and finally giving Yunan control over the realms.
Once both realms were under his control, he could simply teleport members of the council to the realm of the avatars and vice-versa, effective making his words true, each side would think that they were being infiltrated, even if they decided to stop fighting, he could use the dream energy to influence their moods and direct their thoughts, effectively subduing both and forcing them to deal with each other.
Yunan waited patiently for years to enact this strategy, he never used it before so that no one can predict it or think of a counter, as for them discovering the dream energy inside their realms, none of them had ever been to Dreamscape or survived attacks from Yunan while he was using the dream divinity.
