Wolf didn't, but Ranald could insert tarot cards into his deck of playing cards in order to send him a message when Mathilde first met him.
Ranald is specifically called out as a shockingly personable god. Admittedly Mathilde's never seen him talk to anyone without the "magic powers" mutation, which is one of the things she might discuss with Albright if he wins social vote at some point in future.
Is Ranald a shockingly personable god, or wa that from one of storyeater's omakes?
Things like messing with a deck of cards (which could be done by influencing someone to miss-sort them) is the kind of omen I'd expect of a Warhammer god. It's indirect and can be explained away as a very peculiar accident, and it requires interpretation. I could easily see Heidi, for example, using card based divination techniques to communicate with him and interpreting the patterns of the order in which she draws the cards after randomising them as messages from them.
What I wouldn't expect is that they'd be unambiguous or something that can be proved to be divine intervention if someone disputed it.
Just as I'd expect that a Verenan priest might see messages by turning to a random page in a book or similar text based divination. You'd do something in a God's portfolio that they could influence and interpret the result.
Ranald is literally a thief that nailed a godess so hard it elevated him to divinity.
THE FUCKING WIDOW LITERALLY SHITTALKED KHORNE IN FRONT OF US over at original quest.
What part of that is not direct communication. Even if you don't believe Heidi has direct uplink to him, which like, weird, but okay, the rest is quite clear.
Some of Ranald's worshippers believe that he was always a god and ran a con on Shallya where he pretended to be a mortal to steal power from her.
Whether Ranald was a mortal, or whether he's a god that was formed from the legend of a mortal's accompaniment, is something we don't know. The entire story may never have happened at all, just as Ulric probably wasn't originally a god of wolves despite his modern worshippers fervently believing he always was. The gods' mythic histories may well be that, myths. Perhaps with some lesser or greater seed of truth, perhaps without. In the case of Ranald, god of lies and liars, then it seems that the stories his Cult tells of his origin and the least reliable.
And can you quote where we heard the Widow talk to Khorne?
