Lucy looked at Jack curiously,
"So what type of key did you have?" Jack looked at her amused,
"There are several sets of keys as you know. The Zodiac Keys, also known as the Golden Key Set and the Silver Key Set are the most well known. But there is also a Jewel Key Set. Well, honestly my key doesn't belong to any of the three sets. My key belongs to the Seasonal Key Set, of which there are four, including mine." Leo looked at Jack,
"Won't you get into more trouble by telling Lucy this?" Jack shrugged,
"Don't know, don't care. Isn't the first time I've been banished like this." He continued explaining to Lucy, "Weirdly enough there is also a minor key set attached to the Seasonal Key Set called the Holiday Key Set. Those particular spirits are very interesting. Not necessarily useful in battle like the Zodiac Spirits, but more in everyday life. You don't hear about the Animal Key Set often either, perhaps because many of them are tied to the Silver Key Set as well." Jack hummed, "The Nature Key Set is pretty cool too." Lucy smiled at him,
"Do you think you could tell me any more information about the various key sets?" Leo shot her a look which instantly set Lucy backpedalling, "Only if it doesn't get you in more trouble though!" Jack shrugged,
"Eh. The good 'ol King likes me. He'll probably lift my sentence in five years." Lucy gaped at that,
"But Loke could barely survive three!" Jack looked at her oddly,
"So you aren't aware that the less known and less keys a Key Set has the stronger the Spirits belonging to that Set are?" Lucy stared at him before murmuring defensively,
"No I did not know that." Leo slapped Jack on the back of the head hissing,
"Jack, you fool! Humans, Celestial Spirit Mages or not, are not supposed to know that information!" Jack looked weirdly at Leo,
"What in the world are you talking about? Shouldn't it be common knowledge?" Leo face-palmed,
"I forgot that you haven't been down for centuries and as such were never briefed on the rules." Lucy turned her attention to Leo,
"Wait, what now? But if he just got banished then how has he not been down to Earthland for centuries?" Leo turned to his master and explained,
"The Seasonal Key Set keys are extremely rare and as they have duties to perform, it is extremely hard for a Celestial Spirit Mage to find one, so they are almost never contracted. Jack happens to have contracted with a total of three mages, all of them suffering from his power." Lucy looked confused,
"Suffering from his power?" Leo looked away not answering. Jack, however, replied breezily,
"Owning certain keys can have certain side effects on the owner. Moreso if the owner already suffers from various certain ailments. Spring's key, Toothiana's key, can make its owner constantly happy. Specifically it boosts its owner's mood. Summer's key, from what I've heard, makes its owner more likely to go into a rage. Whether of passion or anger I don't really know. I don't socialize with the Summer Spirit. The Autumn Spirit often makes his owner calmer, more reasonable. And then there's my key. Unfortunately many people find winter to be a miserable time of year. Owning my key just makes that misery increase." Lucy stared at him, barely able to comprehend what she was hearing.
