You can take them with you at the end of chapter one, if that’s what you mean. The way to get the option to show up is:
- Be a collector of Arthuriana.
- Don’t be a serial killer (they use a knife instead).
- Go into your apartment with Adrian.
- Select the “Nothing looks suspicious and that’s very suspicious in itself! I’m going for my weapon and checking out every inch of this apartment.” option.
- When you wake up, first select “Freeze. Don’t move a muscle. Just don’t. Don’t. DON’T.”
- Next, select “Frozen. Absolutely frozen. I’m not moving.”
- Then select “I tear my weapon free.” This breaks Excalibur.
The option to pack the broken shards of Excalibur should now show up.
