What are some examples of irony in Stardust?

In "Stardust," some examples of irony include Tristan realizing that his true love was right in front of him all along, only to lose her once he achieves his goal of retrieving a fallen star. Another example is the character of Captain Shakespeare, who is expected to be a ruthless pirate but is revealed to have a kind and sensitive side. Additionally, the fate of Septimus, who spends his life hunting for a star only to ultimately meet his demise due to his obsession, can also be seen as ironic.
