Carnwennan Dagger

Prop Making Project, 2023
The Story
​
420AD - 10 years since the Romans left Britain and there has been a lot of infighting across the country. Myrddin Emrys declares that they will be united again under one king, but only one who is worthy. He enchants a Roman Pugio with the ability to cloak its user in shadow, protecting the future king from harm.
100 years later, Prince Arthur stumbles upon a cromlech. Inside he finds the dagger resting in an alter. Although the alter is aged the dagger looks newly forged. He soon realises that when he holds the dagger no one around him can see him, but is this a blessing or a curse....
​
A skill workshop in prop design and making, with the brief to create the dagger 'Carnwennan' from Arthurian mythology, along with its sheath. The brief detailed that we must outline a short fantasy TV series, set in 6th century Wales. ​
