Keeping abreast of all the different eras between worlds that were not his own, were a special interest of the Archmage Mordenkainen. Seeking the patterns that rippled throughout the planes and crystal spheres of reality continued to prove that no action was without consequence, and no matter was truly trivial.
He'd seen the results of a chance meeting in the village of Hommlet turn into great political intrigue, a revival of the Cult of Elemental Evil, and a slain prince at the battle of Emridy Meadows...
And his own actions to free the demon princes from their bindings in the temple alongside Tasha, as well as the aspects of the demigods in the Godtrap underneath the Greyhawk Castle...
Which in turn caused the fracture of his original Citadel of Eight, the formation of the new Circle of Eight, and the eventual uprising of Iuz and the Greyhawk Wars.
Yes, he thinks, my own actions have caused events to spiral outside of my own predictions, despite my care.
He still did not regret any action taken. As much as the "good" forces of Oerth reviled him for freeing the demonic aspects, they did not see the tears and corruption that was poisoning the earth around the Temple. Were the inhabitants of Hommlet thus disposable for the sake of "good"?
Everyone had their reasons, he supposed. But he found those terms unacceptable.
It's along this train of thought following actions and consequences across the crystal spheres, that a figure of quite some legend on the sister world of Toril, caught his attention.
I've seen those statues, he thinks.
Baldur- or Balduran, a renowned seafaring trader, and the namesake of Baldur's Gate.
Yes, he disappeared after his second voyage, if I recall. Did he disappear to here?
How long had he been here?
This was a great opportunity to learn about the different eras this world pulled from, so without any hesitation, he approaches the man:
"Are you, by chance, Balduran?"
