Born at this point in Leo season
Born in the final stretch of Leo, this person arrives as the summer's fire is starting to burn lower. For years they have been the one who brings energy to a room, and letting that role slide feels like losing a part of themselves. Their fixed nature gives them stamina and loyalty to the things they care about. The harder lesson is knowing when to step back and let someone else take the centre. Their warmth is real, and it lasts longest when they share the light.
