I'm not sure exactly. It depends on how you define a story within The Shard. Maybe you could look for a detailed index or summary to get a precise count.
In 'A Shard of Glass' short story, it might be about a single shard of glass which could symbolize many things. It could be a broken piece of a past, like a broken relationship or a shattered dream. For example, if the story is set in a post - apocalyptic world, the shard of glass could be a remnant of a once - great civilization's architecture, representing the loss and fragmentation of society.
Egg shards can be found in various locations in Monster Hunter Stories. They might be near monster nests or in hidden areas within the game's different regions. Keep exploring different zones and investigating any suspicious looking spots.
