The Game of Whispers

Does the game of whispers still apply to Minalan at this point?

1. It's well known among the common folks, the nobility and clergy that he's blessed by the Gods hence the Snowstone, Everfire, divine visitations, divine stampede and Ishi's Night. Those are just the public manifestations. He's also built too many temples and donated too much to the clergy.

2. He's well loved by the peasantry and has everything in his power to make their lives better and Vanador's first harvest season proved that. The enchantments he's created has eased the people's lives for the most part.

3. His family is too well defended to be easily harmed and should anyone do so he won't hesitate before seeking retribution (at least that's what the Mother's Family thinks). Greenflower proved that to everyone.

4. He himself is heavily guarded in his many castles and his skills in war magic are such that you can't beat him on the field and assassins can't get past his wards.

5. He wasn't born Imperial so he doesn't indulge in the political intrigue and espionage that they are known for. They try to hide what they are doing or obfuscate which limits their avenues of attack while the Narasi tend to be upfront with their actions. Instead of sending assassins he'll send an army or warmagi to remove his problems and he won't hide it.

At this point the man is a living legend to the magi and people at large plus he's cultivated the loyalty of everyone who was strong enough to oppose him early on. He avoids the royal and ducal courts like the plague and they can't discredit him since he's racked up too many wins for the kingdom. They can't take him on the battlefield because of his talents and he has multiple armies behind him. They can't turn the clergy against the man their Gods have clearly chosen as their point of contact among the humans. His allies are loyal and the common people love him.

Is it even possible for the royal family or any of the ducal families to move against him?
